This commit:
* Adds licensing informations.
* Uses the apr-1-config script instead of pointing apr-util to the
apr build directory.
* Ensures apu-1-config gets fixed properly using the
<pkg>_CONFIG_SCRIPTS mechanism.
* Ensures that libiconv gets built before apr-util if available, so
that character set conversion features of apr-util can be enabled.
